Our league is a bit different in that the season spans across two calendar years (i.e. starts in October and finishes in March) as we play based in Australia so the Australian spring and summer for our season.
We have just transitioned in to January of 1998 and we have no stats showing in the daily game log, however stats are being correctly added to the 1997 game year for games played in Jan 1998.
See iamge below for a player traded to Eastern Suburbs in Jan 1998 who has stats for 1997 with EAS but no games listed in the daily game log:
We';ve been running our league this way in every OOTP version since 13 or 14 and never had this issue, seems this is yet another thing that got broken in ootp 21 when it was working perfectly fine before. Please look in to this ASAP ootp.
Nor do stats for Jan 1998 show up in the Game log under the batting stats menu.
